Question 2 (1+3 = 4 marks)

1. Calculate the number of Hamming parity bits needed to detect and correct a single-bit error in a string of 6 data bits.
2. Data has been encoded using an even-parity SECDED code. The binary code was then retrieved as 50B₁₆.
   1. Has an error occurred? Explain your answer (and show your working).
   2. If there was an error, either correct it reporting the correct binary string or explain why it could not be corrected. For full marks you must create a table showing all the parity bits,

• If you were able to correct the error, what ASCII character was originally encoded?
